ST3GAL6 and breast cancer: Accordingly, our results showed LFNG expression was lower in basal/claudin-low breast cancer compared to other subtypes and normal group (P-value < 0.0001) while ST3GAL6 has the highest expression in basal/claudin-low breast cancer (P-value < 0.0001) (Fig. 1a, Tables 1 and 2).
